It is certain that in at least nine cases out of ten a response is
produced, not by an image or other representation of it, but by a
situation nowise like it or any of its accessories. Hunger and the
perception of edible objects, far outweigh ideas of grasping, biting and
swallowing, as causes of the eating done in the world. Objects sensed,
not images of eye-movements, cause a similar overwhelming majority of
the eye’s responses. We walk, reach and grasp on most occasions, not
because of anticipatory images of how it will feel to do so or verbal
descriptions to ourselves of what we are to do, but because we are
stimulated by the perception of some object.
It is also certain that the idea of a response may be impotent to
produce it. I cannot produce a sneeze by thinking of sneezing. A child
may have, in the case of some simple bodily act, which he has done in
response to certain situations thousands of times, as adequate ideas of
it as are possessed by others, and yet be utterly unable to make himself
do it; many adults show this same phenomenon, for instance, in the case
of swallowing a pill. And, of course, one can have ideas of running a
mile in two minutes, jumping a fence eight feet high, or drawing a line
exactly equal to a hundred millimeter line, just as easily as of running
the mile in ten minutes, or jumping four feet.
It is further certain that the thought of doing one thing very often
results in the man’s doing something quite different. The thought of
moving the eyes smoothly without stops along a line of print has occurred
to many people, who nevertheless actually did as a result move the eyes
in a series of jumps with long stops.
It is further certain that in many cases where an animal does connect a
given response with the image or thought of that response, the connection
has been built up by the laws of exercise and effect. Such cases as
appropriate responses to, ‘I will go to bed,’ ‘I will get up,’ ‘I will
eat,’ ‘I will write a letter,’ ‘I will read,’ or to the corresponding
commands, requests or suggestions, are observably built up by training.
The appropriate response follows the idea only if it has, by repetition
or reward, been connected with it or something like it. If the only
requirement in moral education were to have the idea of the right act
at the right time, the lives of teachers and parents would be greatly
alleviated. But the decision to get up, or the idea of getting up or of
being up, is futile until the child has connected therewith the actual
act of getting up.
